HANS PETER GRONBECH, OF PACIFIC BEACH, CALIFORNIA COMBINATION SCREEN AND GLASS WINDOW CONSTRUCTION Application filed June 25, 1930. Serial No. 463,696.

This invention relates to. a combination screen and glass window construction.

An object of the invention is to provide a structure of this class which embodies improved means for ventilation; improved means for regulating the relative amounts of screen and glass area for the window opening; improved means for protecting the screen from the elements; and improved means for attaching and removing the screen and glass for window cleaning or' other reasons.

A still further object of the invention is to simplify and improve upon the general construction relative to the sash, the sash mounting and its supporting and operating means. Other. objects, advantages and features of invention may hereinafter appear.

Referring to the accompanying drawings in which illustrate what is at present deemed to be a preferredembodiment oftheinvention, Fig. 1 is a perspective view of the composite assembly, some portions of the view being broken away to show interior construction. Fig. 2 is a perspective sectional view of the portion of the screen mounting means shown at the left side of Fig. 1.

Fig. 12 is a section taken on line 1212 of Fig. 1.

Fig 13 is a section taken on line 1313 of Fig. 1.

Fig. 14 is a section taken Fig. 1.

Referring in detail to the drawings in Fig. 1, I show a window unit consisting of a stationary central sash 1, and a sidewise sliding sash on each side thereof whichisadapted to slide in front of the stationary sash when it is desired to open the sliding sashes.

Each sliding sash is preferably made about one-half the width of the stationary sash, so that when they are in the full open position they consume the same space as that occupied bythe stationary sash. 1 g

The sliding sash on the right is designated by the numeral 2. In Fig. 1, saidsash 2 is shown in fully opened position. It is also seenflin this position in Fig. 8.

The sliding sash on the left is designated by the numeral 3. In Fig. 1, said sash 3 is shown in partly open and partly closed position and, by also referring to the view shown in Fig. 8, especially to the left hand portion thereof, the relative position of the sliding sash to the stationary sash 1 when the former is in the fully closed position may be clearly noted. The particular interlocking of the twosashes shown in this portion of the view just referred to and making aweather proof joint will be described more in detail later on.

The combination of sashes shown in Fig. 1 may be easily varied to constitute other combinations as well. For instance, a variety of sizes may be practical by having a single stationary sash and sliding sash of the same size, or a triple window may be desirable, wherein the central stationary sash is made the same width as the sliding sashes positioned at either side.

However, the preferred embodiment of the invention shown in Fig. 1 will serve for the purpose of disclosure, it being understood changes coming with the scope of the ap- 0.. line 14-44 ofpended claims may be resorted to when not departing from the spirit of the invention as therein claimed.

The sash members are all substantially U shaped and made of steel which make them fireproof. By reference to Fig. 8 a transverse section of all the sashes may be had which illustrates their construction. In Fig. 12 will be noted a section thru the bottom frame and sash member and in Fig. 14 will be noted a section thru the top frame and sash member.

In Fig. 12 however, it will be noted there is a slight divergence from the true channel U shape in the bottom sash member when contrasted with that in the other views, the reasons for which, will be explainedlater.

In Fig. 8, 4 designates the right hand upright sash member of the stationary sash and 5 the left hand upright sash member, and in Fig. 14, 6 designates the top sash member.

In Fig. 8, 7 designates the right hand upright sash member of the right hand sash, and 8 its left hand upright sash member, while 9 designates the right hand upright sash member of the left hand sash, and 10 the left hand upright sash member of the same. In Fig. 14 the top sash member of the two latter sashes is indicated by the numeral 11.

The stationary sash is provided with a top flange 12 and the sliding sashes are each provided with a top flange 13, said flange being shown in Figs. 3, 4, 5and 14.

Along each flange of the sliding sashes as indicated by the numeral 15 in Fig. 14, is a slot thru which to insert the glass in its respective sash member.

After the glass isinserted thru the slot in its respective sash member it is held against the outside flange of the sash member by a fillerstrip, the channel U shape being made sufficiently deep to accommodate both the Width of the glass and the fillerstrip.

In 8, 16 indicates the right hand fillerstrip for the stationary sash, and 17 indicates the left hand fillerstrip, and in Fig. 14 the top fillerstrip is indicated by 18 for the same sash.

In Fig. 8 the right hand fillerstrip in the right hand sliding sash is indicated by 1.9, and 20 designates the left hand iillerstrip. In Fig. 14 the top fillerstrip of the same sash is designated by 21.

In Fig. 8 the right hand fillerstrip in the left hand sliding sash is indicated by 22, and 23 designates the left hand fillerstrip. In Fig. 14 the top fillerstrip is again designated by 21. l

In Fig. 12 the lower fillerstrip is designated by 24. In the same figure it will be noted the lower fillerstrip for the stationary sash is omitted, it being supplanted by a metal strip 25, the purpose and function of which will be described later.

All the hereinbefore described fillerstrins are held in friction tight engagement with the glass and sash member, and by their employment the work of re-glassing is made very quick and simple.

To the upright sash members 8 and 9, as seen in'Fig. 8 are attached throughout their extent angle weatherstrips 26 and 27 respectively. Said weatherstrips each having a leg 28 oppositely disposed to the other which extends slightly beyond the sash member to which it is attached so as to engage with the side edges of the sash members 4 and 5 when the sliding sashes are in the closed position. The latter position is shown in Fig. 8 when the leg 28 engages with the flange 5. There is provided a groove 29 in each fillerstrip 16 and 17, so as to permit of the engagement of the leg 28 with the flange of its cooperating sash member just described.

On further inspection of the interlocking feature just described, it will be noted the joint is not only weatherproof but the sash members 5 and 9 as well as the frames 4 and 8 when made to assume the closed position, present an appearance as a window mullion which breaks the monotony of the glass and is pleasing and attractive to the eye.

To the upright sash members 7 and 10 on the outer side of the sliding sash are detachably fastened roller screens 30 and 31, which follow the sashes 2 and 3 when opened and disappear when they are closed.

Thus no screen is necessary except for the opened area, there being no exposed screen to obstruct the vision of the eye.

. The sashes and screens are manually operated and held in place by a metallic frame 32, see Fig. 11, said frame is pressed from sheet metal material and comprises a header frame member 33, a base frame member 34, and upright frame members and 36 on the right and left sides thereof, there being provided in conjunction with the two latter frame members a detachable side cover 37, the removal ofwhich affords access to and inspection of screen and roller as well as facility in the replacement thereof. Said cover is attached to the header frame member 33 and base frame member 34 by means of screws 38. The frame. 32 is mitered and welded together and it, together with the sashes and screens come assembled from the factory ready for the installation as shown in Fig. 1.

By referring to Figs. 3, 4, 5 and 14 it will be seen the header frame member33 is provided on its bottom portion with a slotted opening 39. At the outside edge alongside said slot is fastened by wood screws 40 a hard maple strip 41 which runs the full width of the frame 32. On the inner side of said slot and at each side-of the stationary sash over the sliding sash is fastened by wood screws 42 an adjustable hard maple strip 43, there being provided slots 44 in the header frame member 33 to permit of the adjustibility aforementioned, said slot being designated by its numeral in Figures 3 and 4. The strips 43 serve as guides for both the movable sash and screen at that point.

As aforementioned the stationary and movable sashes are provided with flanges 12 and 13. The flange 12, as shown in Fig. 14, extends slightly beyond the inside face of the stationary sash to provide a surface for the flange 13 of the sliding sash to slide upon. It also serves as a Weatherstrip, and cooperates with the strip 41 over the stationary sash to make that portion of the window structure waterproof.

On the sliding sashes the flange 13 is placed even with the outside face of the sash. In Figs. 3 and 4 it may be seen how the flange serves as a Weatherstrip and cooperates with the woodstrip 43 to form a weatherproof condition for V the sliding sashes when they are in closed position and further how the flange cooperates with the strips 41 and 43, also shown in said figures to form a guide and hold the sash in place.

Between the end of the two adjustable strips 43, a portion of the bottom flange header of frame member 33 throughout the width of the stationary sash is cut back increasing the size of the slot 39 on the side of the sliding sash so as to allow it to be raised off its track when in open position and removed for cleaning purposes. This feature is very practical, especially when a building structure consists of several floors.

In Fig. 14 it will be observed that the slot 39 at the point in front of the stationary sash is wide enough to elevate the sliding sash therethrough. At this point and also throughout the width of the increased slot accommodating the raising of the sliding sash for removal purposes, is placed a sheet rubber piece 45 which covers the extra slotted area, said sheet rubber piece being fastened to the header frame member 33 between the ends of the strips 43 by means of a woodstrip 46, wood screwed to the header frame member 33, the rubber strip being engaged between the two.

The assembly of the stationary sash 1 within the metal frame 32 will now be described with special reference to Figs. 5 and 12. At each end of the top channel U sash member 6 is fastened a pair of dowels 47, which projects thru holes 48 in the header frame member 33 into the strip 41.

Onto the base frame member 34 is also welded a key strip 49, said key strip being the width of the stationary sash. There is also a metal strip 50 welded to the flange 51 which rests on said key strip when the stationary sash 1 is inserted in position, the manner in which the sash is mounted in the frame proper being as follows: The sash is grasped on the right and left hand side and brought in position so as to feed the dowels in their respective holes. As the sash is brought forwardly the metal strip 50 will be brought to rest upon the key strip 49 until the flange 51 contacts with the face of the key strip.

The removable metal strip 25 is then screwed to the strip 50 by means of screws 52 thus holding the stationary sash in place and providing a weatherproof condition at that point. This construction also eliminates the flllerstrip at that point. In case the glass is broken by removing the strip 25, thebroken particles of glass can be removed from thesash thereby freeing the fillerstrip. After removingthe fillerstrlp a new glass may be inserted, the fillerstrip replaced and the metal strip 25 added, thus completing the operation.

It will also be noted in Fig. 5 that the dowels 47 cooperate with the flange 12 and the wooden: strip 41 to hold that side of the sash firm and free from rattling.

The description of the mounting for the sliding sashes now follows in detail. In-* wardly disposed with relation to the key strip 49 is a brass angle rail 53 which is fastened to the base frame member 34 and upon which the sliding sashes are adapted to slide. The bottom sash member of the sliding sash as shown in Fig. 12 is substantiallyH shaped, the two top flanges 54 and 55 holding the glass and fillerstrip 24 while into the bottom portion is placed a piece of hard maple wood 56 saturated with oil. The maple wood sliding piece 56 carries the sash and is impregnated with oil to reduce friction as it slides on the brass angle mounted upon the base frame as aforesaid.

There is a notch 57 in said piece 56 which cooperates with the flange 58 to form a saddle upon which the sash is carried by the angle.

There is further provided a pair of screws 59 one at either end of piece 56 which may be brought to bear on the web 60 whereby to adjust the sash inits proper position within the main frame. y V

The detail of the window frame and sash structure combination having been described, the mounting of the screen, so as to operate with the sash and the'operating means will now be described.

In Fig. 2, I show one form of screen roller in which is mounted a spiral spring 61. When it is desired to move the sliding win dow screen to open position tension is put in the spiral spring 61 suflicient to cause it to rotate again thereupon when the window is moved to window closing position.

Since this form of screen mounting is an alternate construction, further description will be dispensed with here in order to elaborate more in detail regarding the preferred screen roller mounting shown in Figs. 6, 7 and 13.

There is fastened to the upright edge of each screen and 31, see Figs. 3, 8, 10 and 13, a screen end strip 62; having a laterally extending flange 63 which is adapted to be attached and detached to the sliding window upright sash members 7 and 10 by means of a plurality of locking lugs 64 preferably three in number.

Said flange 63 is provided with apertures 65 thru which to extend said locking lug. There is provided a locking head 66 on the locking lug 64 and there is a locking aperture 67, see Fig. 4, in said upright sash members, with which each of saidlocking head 66 cooperates in each instance, whereby the screen is secured to the sash. Said looking head being adapted for attachment with the frame when placed at right angles to the screen half of the window, and when rotated thru an angle of 90 to parallel position with relation to the screen window causes the locking head to interlock with the locking aperture inwthe window sash. There is a spacer channel 68 mounted within the sash members 7 and 10 to provide a space 69, see Fig. 13 in which the locking head 66 may operate.

-Means whereon the screen is wound and unwound as the sliding window is closed and opened and manually operable means for performing this function is illustrated in Figs. 1, 6, 7,12 and 13.

These views disclose a rotatably mounted screen roller 70 adapted for manual opera.-

tion producing both clockwise and counter clockwise rotation. On to the bottom of said roller is fastened a female disc clutch 71 adapted'for engagement with a male clutch 72. To the shaft portion of said male clutch is attached a sheave or pulley 73 over which travels an operating cable 74;. There is a sheave 75 mounted within the base frame member 34 as shown in Fig. 12. The sheave is mounted on a shaft 7 6 which is journaled in bearings 7 7 and 7 8. In one end of the shaft is a recess portion 79 and diametrically ar-- ranged in said recess is a pin 80.

Into said recess is adapted to be projected a forked shaft 81 which rides astride the pin 80, and to said shaft 81 is secured a crank 82 which may be manually operated to rotate sheave 7 5 thru the medium of said pin 80.

The cable 742 travels over the sheave 75 and has one end 83 fastened to the extremity of a T shaped. metal connector 84. There is an eX- tension 85 fastened to said connector whereby it is applied to the sliding sash by means of a screw 86 as shown in Figs. 1 and 9.

There is a slot 87 provided in the base frame member 34 into which said extension projects and along which it travels. The other end 88 of the cable is fastened to aturnbuckle 89 and said turnbuckle is fastened to the other extremity of the connector 84. Applying traction to either end 83 or 88 of said cable 74, simultaneously slides the sliding sash and winds up or unwinds said screen.

In Fig. 13 the detachable side cover 37 is provided with an inturned flange 90 and over the bent portion is applied a standard weatherstrip 91 similar to that used on automobile Windshields, so as to make that portion of the sash structure weatherproof.

The component sashes and frame may be assembled in the factory, shipped directly to the job and installed in a few minutes. The window construction is fireproof and weatherproof, no ugly black screen beingon the outside to mar the beauty of the structure.

In Fig. 1 there is a composite construction illustrating the appearance of the window when surrounded by an appropriate wood trim. The wood trim and the mouldings applied thereto are supplied as a matter of taste, providing a setting which enables one interested in a new and novel device to view the same to advantage. This device is not only suitable fordwellings but office and income buildings as well.
